To all whom it mayconcem:

Be it known that I, WILLIAM Dinrniori, a citizen of the UnitedStates,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Casting-Machine, of which the following is aspecification.

My invention relates to casting machines for casting rectangular blocksof metal in which the size of the mold for the block can be varied insize, and the objects of my improvements are first, to retain the moldin a rectangular form; second, to make two sides of the mold movable;third, to provide means for retaining the one movable side of the moldin arectangular position to the balance of the mold while being moved,

fourth, to provide sliding blocks on two opposing sides of the mold toassist in forming one movable side of the .mold; fifth, to provide meansfor securing the different sides of the mold in proper position; sixth,

tomake a neat, cheap and elficient device and other features to becomeapparent from the description to follow. I

As above mentioned my invention pertains to machines for castingrectangular blocks of metal, the blocks being used in the art ofprinting for securing a page of type into achase and for any othersuitable purpose. In the use of these rectangular blocks it has beenfound that work is greatly facilitated by forming or casting the blocksas fast as they are needed and after they have served their purpose torecast them into other blocks of different sizes as again required. Thiseliminates the necessity of keeping a large stock of blocks on hand andthe danger of mutilating the blocks by oft handling.

To describe my invention so that others versed in the art to which itpertains can make and use the same I have-illustrated it on theaccompanying two sheets of drawings forming a part of this specificationin which r Figure 1, is a plan view ofa machineembodying my invention;Fig. 2, is a. fragmentary plan view showing one side of the mold movedto an open position; Fig. 3, is a cross sectional view taken on line 3-3of Fi 1, and Fig. 4, is a cross sectional view ta en'on line 4-4 of Fig.1.

Similar reference characters refer to similar parts throughout theseveral views:

. 'The mechanism is all mounted on a horizontal metal table '5 ofsufiicient thickness and which preferably has the depending renforcingflange 6 at its four edges. The table 5 1s rectan ular in shape and ofany desirable size. ecured rigidly to the top ofv the table 5, by meansof screws 7 or otherwise, are the three metal bars 8, 9 and 10 to formthree sides of a rectangle. The bar 8 being locatedat the front edge ofthe table 5, the bar 9 being located at the left hand endof the table 5and the bar 10 being located at the rear edge of the table 5.. At therlght hand edge of the table 5 is provided a. bar' 11 forming the fourthside of the rectangle formed by the bars 8, 9, 10 and 11,- which ispivotally secured to the rear edge of the table 5 at 12 to swing in ahorizontal plane. The free end of the bar 11 is detachably secured inposition against the right hand end ofbar 8 by a pin 13 fitting snuglyinto a hole provided therefor in the bar 11 and fits snugly to the table5 and against the end of bar 8 so that molten metal cannot escape pastthe same.

A bar M is mounted to slide freely laterally forward "and back on thetable 5 and has attached to each-end by means of a. screw or pin, 15 arackbar 16 which rackbars extend rearwardly from the bar 14 along besidethe bars 9 and 11, through guide-ways 17 rovided therefor in the underside of the ar 10 asseen in Fig. 4.

The bar 1 1 is of such length as to fit between the bars 9 and 11 andlies parallel to the bar 8, and as said bar 14 is moved toward and awayfrom the bar 8 it is retained parallel-to the bar 8. The bars 14, 11 and8 form three sides of the mold into which the molten metal is poured,therefore the bar 14 also fits snugly to the table 5 and against theside of bar 11. The bar 14 is moved as desired toward and away from thebar 8 by manipulating the hand wheel 18 which is rigidly secured to theshaft 19 mounted in bearings 20 integral with or mounted on the bar 10.Rigidly mounted on the shaft 19 are the two small gears 21 which are inconstant mesh with the rack bars 16 'so that as the shaft 19 is rotatedthe gears 21 will movethe rack bars 16 in unison, which of course willalso move the bar 14. To secure the barl i inany desired position a setscrew '22 is proyidedin one of the bearings 20"to take against the .haft19. 1t isd vious that preventing the shaft 19 from rotating will holdthe bar 14 against move-- ment. 7

The edge of'the bar 11- adjacent the bar 14 is graduated at 23 to enablesetting the bar 14 at the required distance from the bar 8 whichdetermines the width of the block to be cast.

To determine the length of the block to be cast a pair of adjustableguides are slidably mounted on the bars Sand 14, the guide 24 is mountedon bar 8 and the guide 25 is mounted on bar 14, and each is constructedlike the other with. a set screw26 for securing it in any desiredposition on its co6perating bar. Each bar 8' and 14 is provided -withgraduations on one edge at. 27 with which the guides 24 and 25cooperate. The- I said graduations are spaced exactly the same.distances from the bar 11 so that if a rule or other metal piece islaid against the two guides 24 and when they are set at correspondingfigures, said rule or other metal piece will be parallel to the bar 11as indi- 14 is set at the figure on the graduations 23' to correspond tothe width of the desired block,vand the gages 24 and 25 are set at thefigure on the graduations 27 to correspond to the length of the desiredblock.

Care is taken that the free end of thebar 11 is secured in positionagainst the end of the bar 8 by pin 13. A rule 28 of proper length isplaced against the two guides 24 and 25; then the molten metal is pouredonto the table 5 within the confines of the rule 28 and bars 8, 11 and14. After the metal has sufiicient-ly hardened, the pin 13 is withdrawnand the free end of bar 11 is swung to the right about the pivot 12, asshown in Fig. 2, and the block of metal is pushed out of the mold to theright. After the cast block is thus removed from the mold the free endof bar 11 is again returned to its position against the end of bar 8,and the machine is in position for casting another block of the samedimensions. The pin 13 is preferably prevented from becoming detachedfrom the table 5 by means of a small chain or cord. I
